### How do you find the percentage rate?

2. How to find what percent of X is Y. Use the percentage formula: Y/X = P%

1. Convert the problem to an equation using the percentage formula: Y/X = P%
2. X is 60, Y is 12, so the equation is 12/60 = P%
3. Do the math: 12/60 = 0.20.
4. Important!
5. Converting 0.20 to a percent: 0.20 * 100 = 20%
6. So 20% of 60 is 12.

What is the difference of rate and percentage?

A rate can only be expressed as a percentage if the rate is measured as a ratio, since a percentage is a ratio in the form x:100. Look it in another way. The rate is the thing you measure.

What’s the difference between rate and percentage?

“Rate” simply means the number of things per some other number, usually 100 or 1,000 or some other multiple of 10. A percentage is a rate per 100.

## Why is percentage used?

We use percentages to make calculations easier. It is much simpler to work with parts of 100 than thirds, twelfths and so on, especially because quite a lot of fractions do not have an exact (non-recurring) decimal equivalent.
